Domo Broadcast Systems SAPPHIRE RXD3 – Glue Equipment

Yes. The RXD3 includes one 12G-SDI monitoring output via SFP with HD downsampling capability, and supports ST2110 IP streaming via the same SFP interface. You'll need to confirm with Domo whether the SFP port runs ST2110 *and* SDI simultaneously or requires mode selection. For a full ST2110 deployment, ensure your network infrastructure supports the bitrate of your selected video format, typically 1.5–2.2 Gbps for 4K UHD. Consult your system integrator on timing alignment and PTP requirements.

The RXD3 features 8-way Maximum Ratio Combining (MRC) via 8 × BNC Female RF inputs. MRC automatically weights each antenna input by signal quality and combines them coherently, improving fade margin over single-antenna reception. In an OB van, deploy 4–8 spatially separated antennas (2–4 m apart) fed to independent RF chains. This topology reduces multipath dropout and extends reliable range. Confirm antenna matching and feeder loss with your RF integration partner; poor antenna placement negates MRC benefit.

The unit outputs 4 × 12G-SDI HD-BNC outputs plus SRT streaming capability via its SFP interface. However, confirm with Domo whether SRT encodes a parallel H.265 stream or is derived from the SDI outputs, and whether bitrate/resolution constraints apply to simultaneous operation. If SRT requires a separate encoder instance, power and thermal headroom (50–80W nominal) may be tight in a compact rack. Test your exact workflow with Domo pre-purchase to avoid integration surprises.

Sub-40 ms end-to-end latency is suitable for camera feeds to a mixer and on-air program return. However, talent monitoring via the received signal will exhibit perceptible delay relative to direct talkback, which can disrupt confidence monitoring. For multi-camera OB, treat the RXD3 latency as camera-to-mixer delay; coordinate with your video router and production control for lip-sync. If latency is critical, request latency measurement under your specific RF and bitrate conditions; stated performance assumes optimal DVB-T configuration.

The unit draws 50–80W at 12V DC and requires a dedicated 12V supply (PSU type and redundancy are your responsibility). Half-width form factor allows side-by-side mounting of two units, but confirm your chassis supports dual 12V loads and airflow management. No active fan specifications are listed, so assume passive or low-noise cooling. In a sealed flypack enclosure, monitor intake temperature; inadequate ventilation may reduce RF receiver sensitivity. Plan PSU capacity and redundancy early with your systems integrator.

The unit includes a color touchscreen with day/night modes for local control and web-browser remote access. Specific control protocol support (REST, telnet, SNMP, or proprietary APIs) is not detailed in the specifications. Confirm with Domo whether web control integrates with third-party automation systems (e.g., Ross OverDrive, Grass Valley Ignite) or requires manual web interface access. For unattended OB operation, verify failover and alarm notification capabilities; web control alone may be insufficient for broadcast SLAs.

The standard Sapphire-RXD3 uses H.265/HEVC. The SAPPH-RXD3D variant adds H.264 support if legacy compatibility is required. Video resolutions span 4K UHD 2160p through 720p at frame rates 23.98–60 Hz, with 8/10-bit and 4:2:2 or 4:2:0 chroma. 4K licensing may be required (contact Domo for details). Firmware updates may enable additional profiles or bitrate modes; confirm your required formats are supported *and licensed* for your intended use before committing to this model over the H.264-capable variant.

The RXD3 supports DVB-T modulation (QPSK/16QAM/64QAM), FEC rates 1/2–7/8, and guard intervals 1/32–1/4 across 6/7/8 MHz bandwidths. Lock time and parameter negotiation behavior are not specified; consult the user manual or Domo support for exact lock duration and robustness to transmitter drift. In live OB, always pre-coordinate modulation/FEC with your transmitter operator and include a margin test before going on air. Mismatched parameters cause frame loss; automation should alert the operator immediately.

No specific wear items, firmware roadmap, or spare-parts availability are listed in the specifications. Typical rack equipment requires PSU spares, SFP transceivers, and BNC adapters. Request from Domo: firmware update frequency, available spare modules (tuner cards, power supplies), mean time between failures (MTBF) data, and support SLAs for your service territory. Budget 10–15% of unit cost annually for spares and ensure your supplier maintains stock for OB emergencies. Confirm end-of-life and obsolescence timelines before fleet deployment.

Yes, every used or ex-demo unit is tested and covered by a 90-day warranty. In the event of a failure, the round-trip transport cost is shared equally between the customer and Broadcast Depot.

Yes, Broadcast Depot ships worldwide. We arrange transport on quotation, or you can use your own carrier. Delivery usually takes 3 to 5 days. OB vans are delivered by driver or collected on site.
